Specialized Aethos Comp Rival AXS Disc Road Bike 2022
Designed to offer the finest possible ride quality, the Specialized Aethos Comp Rival AXS Disc Road Bike boasts incredible versatility by excelling in gran fondos, fast group rides and, most importantly, long and challenging café rides.
The full FACT 10r carbon frameset uses a sophisticated material layup within refined, traditionally profiled tubes to heighten pedalling efficiency while keeping the weight super-low. The advanced design of the frameset blends equal measures of front and rear stiffness with extra vertical compliance to result in a superior feel when out on the road, whether climbing, descending or pushing the pace on the flat.
The lively, strong DT Swiss wheels have broad internal rim measurements to help improve tyre comfort and grip and are driven by the SRAM Rival AXS gear set up. These gears use their wireless electronic format to deliver crisp, accurate and reliable shifts every time of asking. The matching SRAM hydraulic disc brakes promise confidence-inspiring stopping power in all conditions, while the Roval Alpinist carbon seatpost dampens road vibrations and keeps the build weight down. A Specialized Power saddle, handlebar and stem complete the bike with comfort and style.
